Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164090, here are decompositions:

19 + 164071 = 164090
67 + 164023 = 164090
79 + 164011 = 164090
97 + 163993 = 164090
103 + 163987 = 164090
109 + 163981 = 164090
163 + 163927 = 164090
181 + 163909 = 164090

Showing the first eight; more decompositions exist.
